Nanoparticles as Developed Treatment Against Leishmaniasis: A Mini Review

External and internal parasites are the two types of parasites that are detrimental to human health. Parasites may live on the outside or within the host. Approximately 200,000 individuals are killed by parasite illnesses each year, which affect 3.5 billion people. In developing countries, these parasites cause fatal diseases such toxoplasmosis, leishmaniasis, trypanosomiasis, and malaria, which have high rates of morbidity and mortality. Endoparasites are organisms that live in biological environments and are a serious danger to human health, whereas ectoparasites are arthropods that transfer specific parasites or cause disease.Leishmania sp. is one of the most important of these parasites. Leishmaniasis is caused by the obligate protozoan parasite Leishmania. Of the many parasite species discovered in this genus, twenty-one are considered pathogens. Leishmania ethiopia, Leishmania donovani, and Leishmania amazonensis are some of the species that cause leishmaniasis. Once an infected person or animal’s blood is consumed by a sandfly, leishmaniasis is spread. The illness causes ulcers, and the infection can spread to other parts of the body. Visceral leishmaniasis (VL), cutaneous leishmaniasis (CL), and mucosal leishmaniasis (ML) are the three primary forms of leishmaniasis. Mucosal leishmaniasis symptoms often take one to five years to manifest. Most treatments for parasitic infections are no longer effective due to parasite resistance and a range of pharmacological side effects, even though many have been discontinued.Chemical drugs and ethnobotanicals were used in the past to treat parasites. Resistance in parasites has been brought about by these chemotherapies. New biotechnologies that will enhance the safety of existing antiparasitic drugs and the accuracy, efficacy, and tolerability of diagnostic tests are thus the greatest means of addressing the problem of the aforementioned parasitic diseases.

Research on pharmaceutical delivery and medical diagnostics are included. Pharmaceutical dosage forms based on nanotechnology are now being manufactured and used widely around the world. Advanced technologies in engineering, veterinary medicine, and medicine are only a few of the many different domains of knowledge that nanotechnology covers. New products based on nanotechnology, such as vaccines, recombinant proteins, and other pharmaceutical alternatives, provide safer environments for humans and/or animals. Biological applications such as drug delivery and issue engineering, bioimaging, and nanodiagnostics are among the many fields that have profited substantially from nanotechnology. Applications of nanodiagnostic methods for infectious diseases are growing in popularity due to their unique high sensitivity and early detection capabilities. Since antibiotic resistance is currently a threat to public health, several sectors have been established and significant progress has been made in the search for new and effective treatments. The development of antibacterial drugs heavily relies on nanomedicines because of their numerous advantages. Parasites, such as worms and protozoa, are common in Iraq. There have been a lot of studies done on diagnosis and treatment.
